                <p><span class="initial-space"></span><strong><span style="color:#c60d0d">IntegralUI</span> PopOver</strong> is a native Angular component that displays custom HTML content over specified element. It provides functionality that allows you to add a popover that will be displayed at specified position, with initial delay and how much time will remain active. This component is inherited from <a routerLink="/tooltip">Tooltip</a> component.</p>
                <p><span class="initial-space"></span>By clicking inside the element space, the PopOver will appear at position specfied in the control panel. The example uses a simple template that contais some text and Ok button, you can modify it and add any custom HTML elements or other Angular components in it.</p>
                <p><span class="initial-space"></span>In this example, there is a control panel where you can set different properties of PopOver component. You can choose the initial delay before popover is shown, how long it will remain visible, position at which will appear and whether it is enabled or not.</p>
                <p><span class="initial-space"></span>If activation is set to 'manual', the popup will remain active until it's closed by changing the popOverShow property to false. If popOverShow property is not specified, then the popover will appear on mouse enter.</p>
                <p><span class="initial-space"></span>The following properties are supported:</p>
                <ul class="feature-points">
                    <li><span style="color:#c60d0d">activation</span> - specifies whether the popup is activated manually or automatically</li>
                    <li><span style="color:#c60d0d">appRef</span> - holds a reference to application view</li>
                    <li><span style="color:#c60d0d">autoPopDelay</span> - specifies the time in milliseconds for PopOver to remain visible</li>
                    <li><span style="color:#c60d0d">closeButton</span> - determines whether the close button is visible in the header</li>
                    <li><span style="color:#c60d0d">enabled</span> - determines whether the PopOver is enabled or disabled</li>
                    <li><span style="color:#c60d0d">header</span> - determines whether the popover has a header</li>
                    <li><span style="color:#c60d0d">initialDelay</span> - specifies the time in milliseconds prior PopOver is shown</li>
                    <li><span style="color:#c60d0d">position</span> - determines where the PopOver will appear: above, below, left or right side of the target element or at mouse position</li>
                    <li><span style="color:#c60d0d">showMarker</span> - when true, an arrow marker will be displayed for the PopOver window</li>
                    <li><span style="color:#c60d0d">title</span> - a text displayed in the header</li>
